In the User Manual section 7.1, we see several sample code snippets such as this one:

JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext();
try {

 // Invoke persistence operations here

} finally {
 jbpmContext.close();
}

All the examples use a JBPMConfiguration instance (jbpmConfiguration), however it is not explained how we get a reference to this instance in the first place. What's the way to do it?
